I'm working on a crawl space encapsulation. One of the last steps for me to do is to setup a dehumidifier. I bought a Santa Fe Compact 70 and a condensate pump to go with it. I'm discharging it about 20 feet away.
It feels as though I didn't really plumb the condensate pump correctly. Here is my setup.
Dehumidifier setup (note, any extension cord you see is temporary only). The condensate pump has a check valve in it and a barbed fitting to a 3/8" ID clear vinyl tube.
I then take that up to my floor joist and create an inverted U as specified by the instructions (basically only thing the instructions say to do).
I then come down and transition to a 1/2" PVC pipe with a barbed fitting. This is my first question. Is it okay that I go from a barbed fitting at the condensate pump to a vinyl tube then have a second barbed fitting that transitions to a PVC pipe? It seems as though this second barbed fitting would create a bit of a bottle neck.
I then have roughly 18' of PVC pipe that has plenty of fall to it. The end of the PVC is at least 1 foot lower than the start
I then transition back to a vinyl tube using a third barbed fitting and into the sump pit
Here is a rough drawing of what I have
Is it bad for me to have those barbed fittings? I could get rid of the third barbed fitting if I wanted to and just stay straight PVC into the sump pit, but the vinyl tubing was easier to work with.
The condensate pump doesn't appear to be working as I would expect. After the highest point, water is sitting in the vinyl tube right before the transition to the PVC pipe. I can see some air pockets as well. I understand that water will be trapped between the highest point and the condensate pump, which is fine because there is a check valve. But I would expect all of the water after the highest point to be drained out by gravity. Here is a quick video of me running the condensate pump where you can see the water sitting near the transition to the PVC pipe and not draining. Here is a quick video of the water exiting the PVC pipe and transitioning to the vinyl tube and into the sump pit.
Any reason why this isn't draining well at all?
